Manufacturered by Leo Bodnar Ltd, the Low-jitter GPS-Locked Precision Frequency Reference Oscillator can be programmed to two output frequencies between 450 Hz up to 800 MHz with a stability of better than 1e-9 (1 part per billion (ppb) within 1 minute after achieving lock to the high accuracy GPS Satellite Network which is controlled by a Caesium Clock with accuracy approaching 1e-12

USB powered, this instrument is the ideal frequency standard for supplying an external reference clock signal to the DG8SAQ Vector Network Analyzer to make Frequency and Frequency Difference measurements with accuracy approaching 1e-10 and frequency measurements (dF) in the mHz mili Herz) and even down to the uHz (Micro Herz) region.

Light and portable, the Precision GPSDO Reference Oscillator can be used as an Universal Reference Clock for most other Instruments and Applications which upto now would require a bulky and expensive Rubidium Clock.

Two synchronised low-jitter reference clocks locked to GPS signal, Digital PLL allows main output reference frequency to have almost any value between 450Hz and 800MHz.

Two outputs can be individually enabled and set to different
frequencies. Important: The Second output frequency depends on the First output frequency. If
both outputs have the same frequency their relative phase shift can be
adjusted. This can be used, for example, to generate two signals with
90° phase shift for use in I/Q mixer but for certain frequencies only.

Both output signals are at 3.3V CMOS levels with 50 Ohms characteristic impedance. Their output drive levels can be adjusted.
